H. S. WILLIAMS COLLAPSIBLE FOUNTAIN SYRINGE Filed May 10, 1930 A TTORNE V Patented Mar. 14, 1933 UNITED STATES HARRY s. WILLIAMS, 0;? DENVER, COLORADO, nssroivon To DENVER, COLORADO i co-LLAPsmLE FOUNTAIN" simmers I Application filed May 10,-

My invention relates to water bags and more particularly to collapsible fountain syringes, and has for its principal objects to reduce the proportionate amount of space required for packing a collapsed bag, to adapt a rubber bag of the bellows type for use as a reservoir of a fountain syringe.

Further objects of the invention are to provide a collapsible fountain syringe or water bag of bellows type, having a circular bottom provided with a central threaded nipple to which the usual rubber'tube having a suitable nozzle, may be coupled; a flat ring being secured by vulcanization to the top of the bag, and connected to the bottom by flexible connections which limit the extension of the bag when the same is filled with water, {)he said flat ring having a hinged supporting ail.

I accomplish these objects by the character of bag or syringe illustrated in the accompanying drawing, in which Fig. 1 is a perspective view of my improved collapsible fountain syringe suspended from a wall hook, a conducting tube being shown fragmentarily, and walls of the bag being partly broken away to better illustrate con-. struction.

Fig; 2 is a perspective View of the device in collapsed position.

Fig. 3 is a perspective view of a container illustrating the collapsed syringe and tube packed therein, the container wall being partly broken away for better illustration.

Referring to the accompanying drawing, the numeral 1 designates the bag proper, which is preferably made of rubber, and which is constructed to be folded or collapsed bellows fashion, after the manner of a Chinese lantern.

To the lower edge of the bag is a bottom 2 having a central hole 3, in which is secured a flanged internally threaded nipple 4. To the top edge portion of the bag is secured a thin flat metal ring 5 by vulcanization, and the ring is connected to the bottom plate by a pair of flexible connections, preferably chains 6, which prevent excessive extension of the bag. A pair of apertured lugs 7 are secured to the ring 5 in which are inserted 1930. Serial No. 451,270.

v the bentends of a bail 8, by which the bag or syringe maybe suspended whenin use,

To the nipple 4: is adapted to be secured a tube .orhose 9, of the character usually employed in connection with the common type of water bag, thetube being provided at one WILLIAM A. BRYANS, or

end with a threaded couplingm ember, 10,

be only fourinches' in "diameter, and when 'which is' screwed in the nipple, as shownin J Afountain syringe, of this character may I collapsed will occupy a space of less than a half inch in depth, so that it may be placed in a hollow case in which the tube 9, after being disconnected from the bottom plate, may also be placed in coiled form, and the case will occupy but a small space, and may therefore be conveniently carried either on the person or in a suit case or hand bag when travelling,

In practice, the bag is suspended from a hook by means of the bail 8 and will extend by gravity to the limit defined by the chains 6; the tube 9 is then connected to the nipple 4, and the bag is filled with water, and is then ready for use. As the bag has a, relatively large opening through the ring 5, it may be;

easily filled with water, and after use may be easily and quickly dried out before being collapsed, and placed in a case, thereby preserving the life of the rubber. While I have specifically referred to use of the bag as a 001- W lapsible fountain syringe, its adaptability for use as a water bottle or ice pack is apparent. I

That I claim and desire to secure by Letters Patent is:

1. A device of the character described comprising a circularbellow-like collapsible bag of water proof material, a bottom for the bag having an outlet nipple for connection,

thereto of a water tube, a flat metal ring;

secured to the top of said bag by vulcanization, a hinged bail secured to said ring at opposite diametric points, and flexible members connecting said ring and said bottom for limiting the extension of the bag. V

2. A device of the character described comprising a bellow-like collapsible ba having an outlet nipple, a fiat ring secured to the top of the bag by vulcanization, a hinged bail on the'ring, and flexible members 5 extending longitudinally within the bag for connecting said ring and the bottom of the bag to prevent excessive extension of the bag.

3. A device of the character described including a bellows bag formed of pliablematerial, a reenforcing member forming the top of the bag, means connected with the reenforcing member for suspending the bag and flexible means connecting the bottom of the bag with the reenforcing member for l) limiting extension of the bag.

4. A device of. the character described comprising a bellows-like collapsible bag of water proof materiaha bottom for thebag having an outlet nipple, ametal ring secured a $9 to the top of the bag, a hinged bail having a pair of arms secured to the ring on atransverse median line thereof, and a pair of chains having one end connected to the ring in alignment with said: arms and the opposite end connected to "said bottom for limiting the extension of the bag. p

In testimony whereof Iaflix my signature.
